According to Finnish-Estonian joint research with data obtained on two crustacean species, there is apparently no reason to consider silver nanoparticles more dangerous for aquatic ecosystems than silver ions. The results ...

Scientists at The University of Manchester have identified the method by which cells control the recycling of molecules, a process that is essential for them to move. The discovery provides researchers with a better understanding ...

During embryo development, genes are dynamically, and very precisely, switched on and off to confer different properties to different cells and build a well-proportioned and healthy animal. Fgf8 is one of the key genes in ...

On the way to the production of environment-friendly fuels from biomass residue, the Karlsruher Institut für Technologie, or KIT for short, in cooperation with the technology partner Air Liquide Global E&C ...

For many so-called apps, developers and companies have not adequately ensured that the mini-programs are actually working the way they should. Therefore, computer scientists at Saarland University developed ...

Agriculture is responsible for around 10 to 12 percent of all greenhouse gases attributable to human activities. This raises the question of how these emissions could be reduced. A recent study has investigated—for ...

A single mutation in the H5N1 avian influenza virus that affects the pH at which the hemagglutinin surface protein is activated simultaneously reduces its capacity to infect ducks and enhances its capacity to grow in mice ...

Tiny particles filled with a drug could be a new tool for treating cancer in the future. A new study published by Swedish scientists in Particle & Particle Systems Characterization shows how such nanoparticles can be com ...

Cockroaches (Blattodea) are an insect order remarkable in their biodiversity and distribution, with more than 4500 species known and great geographical reach. Cockroach fossils date back around 400 million ...

Canola, cottonseed, and sunflower products can replace soybean meal in diets fed to pigs, but they contain less protein and energy. To determine if it makes economic sense to use them, producers need to know the concentrations ...

Max Planck scientists in Jena, Germany, have discovered an unusual regulation of enzymes that catalyze chain elongation in an important secondary metabolism, the terpenoid pathway. In the horseradish leaf ...

To show spatial animations on websites, developers so far have had only two options: to use special software or to implement it from scratch. Computer scientists at Saarland University have developed a declarative ...

(Phys.org)—Astronomers using ESO's Very Large Telescope have obtained what is likely the first direct observation of a forming planet still embedded in a thick disc of gas and dust. If confirmed, this discovery ...

(Phys.org)—Using new technology at the telescope and in laboratories, researchers have discovered an important pair of prebiotic molecules in interstellar space. The discoveries indicate that some basic ...
